Answer:

The selling price would be $420.

Step-by-step explanation:

In order to find the mark up, we need to multiply the amount it originally costs by the percentage it is being marked up.

$300 * 40% = $120

Now that we have the mark up amount, we add it to the original cost to get the sale price.

$300 + $120 = $420

What is the perimeter of trapezoid JKLM? j -7,4 k -4,4 m -8,3 l -2,3
kompoz [17]
Check the picture below.

you can pretty much just count off the grid the units for JK and MI.

now, let's check how long are KI and JM

\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
K&({{ -4}}\quad ,&{{ 4}})\quad 
%  (c,d)
I&({{ -2}}\quad ,&{{ 3}})
\end{array}\qquad 
%  distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}
\\\\\\
KI=\sqrt{[-2-(-4)]^2+[3-4]^2}\implies KI=\sqrt{(-2+4)^2+(3-4)^2}
\\\\\\
KI=\sqrt{2^2+(-1)^2}\implies KI=\sqrt{4+1}\implies \boxed{KI=\sqrt{5}}\\\\
-------------------------------

\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
J&({{ -7}}\quad ,&{{ 4}})\quad 
%  (c,d)
M&({{ -8}}\quad ,&{{ 3}})
\end{array}\qquad 
%  distance value
\\\\\\
JM=\sqrt{[-8-(-7)]^2+[3-4]^2}\implies JM=\sqrt{(-8+7)^2+(3-4)^2}
\\\\\\
JM=\sqrt{(-1)^2+(-1)^2}\implies \boxed{JM=\sqrt{2}}

so, add all sides, and that's the perimeter of the trapezoid.

viktelen [127]

Answer:

39600 words

Step-by-step explanation:

Given data

In 1 minute, Alex can type 44 words

from 10:00 AM until 1 AM= 15 hours

15 hours to minutes= 15*60= 900 minutes

Hence in In 1 minute, Alex can type 44 words

            in  900 minutes he will type x words

cross multiply

x= 900*44

x= 39600 words

Hence he will type 39600 words

Point D is on segment BC, Segment BC measures Bx
Nostrana [21]

Answer:

144 units

Step-by-step explanation:

3x + 8 + 4x + 10 = 8x

7x + 18 = 8x

8x - 7x = 18

x = 18

8x is length of BC

8 × 18 is length of BC

144 units
